Motorists may be inconvenienced Tuesday night and Wednesday morning by construction along the Interstate 20-Texas 183 corridor in southwest Fort Worth.

But the good news is, work in that area -- much of it related to the planned Chisholm Trail Parkway toll road -- is nearly complete.

Beginning at 8 p.m. Tuesday, crews are scheduled to demolish what's left of the Texas 183 overpass at Bryant Irvin Road. During that time, Bryant Irvin Road traffic will be detoured, and motorists should expect delays, a Texas Department of Transportation spokeswoman said.

However, access to area businesses will remain open, she said. Police officers will direct traffic to detours.

Traffic on Texas 183 won't be affected. That road, also known as Southwest Boulevard, will remain open with one lane of traffic in each direction, as workers continue to build a permanent 183/Bryant Irvin Road bridge over the next four to five months.

The project is a partnership between the Transportation Department and the North Texas Tollway Authority. The Transportation Department's portion adds up to about $117 million worth of work, including new bridges, access ramps and frontage roads and the lowering of the Texas 183 main lanes.

"Our part of the project is set to complete by spring and summer, by May or June," Transportation Department spokeswoman Jodi Hodges said.

The tollway authority is building Chisholm Trail Parkway, a planned 28-mile toll road from I-30 near downtown Fort Worth to U.S. 67 in Cleburne. Tollway authority crews could still be doing work in the I-20/Texas 183 area for the Chisholm Trail Parkway's main lanes, as the agency strives to open the toll road by 2014.
